230VAC Triac Dimmable GU10 LED Driver
General Description
This AP1694A Triac Dimmable GU10
12V/400mA Buck LEDs driver EV board use
tapped transformer to increasing power
conversion turn on duty cycle, boost
current back to LED during ratio of tapped
winding. Also the bigger gauge wire can be
used as well as the large inductance can be
suitable in switching loop which can reduce
the switching current and the lower
forward drop so that SBR diode can be used
which can reduce the power consumption
on the diodes.
